Application filed July 11, 1918 Serial No. 244,473.

To all whom it may concern:

]Be it known that I,'CLARENGE a citizen of the United States, and residing at Rochester, Monroe county, State of New York,.have invented certain new and useful Improvements in Paper-Fasteners, of which the following is a specification;

The present invention relates to paper fasteners of the type comprising a backing member having spaced projectmg. flexible tongues and a front or top'm'ember through which the tongues are passed. a

The principal novelfeatures of the in" vention reside in the provision-of a backing member in which thetongues are spaced slightly from the ends thereof'wh'ereby the backing member isf-formed with-end portions which bear against the under sheet outside the perforations therein, thusgre inforcing the sheet against tearing; 1n

ing the end portions aforesaid in which the tongues are longer than half the dis tance between the tongues; in the provision of'a backing member having the said end portions and one tongue struck up from the member and being longer than half the distance between the tongues; in.

the provision of a backing member having the said end portions and a ton ue connected thereto by apiece extending rom the foot of the tongue to the adjacent end of said f member; in the provision of a front memher having end portions bearing on-the top sheet of the file throughout the area sur rounding the perforations therein; in the provision of a front member having'end portions and a connecting part adapted to the provision of a front member having end portions and a connecting-part of less width than the end portions; in the provision of a front member having end portions each formed with an aperture and a connecting part, the joints between said part and portions being offset from the line connecting the apertures, and generally in the provision of a dependable, easily manipulated fastener which requires a minimum. of ma-' terial in its manufacture. Other features- .of novelty will be apparent from the de- I i a file of sheets held together by a fastener G. FISHER,

constructed in accordance with the present 1nvent1on;

Fig. 6 is a view illustrating in bottom' plan a portion at one end of member shown in Fig. 53 k Fig. 7 is a plan view, similar to Fig. 1 illustrating a modified form of front mem- Fig. 8 is a top plan view similar to Fig. -7 illustrating another modified form of front member;

the backing Fig. 9 is a perspectivelview of a modified I form of backing member;

*' Fig. 10 is a sectional elevation through an ,end portion of the member shown in Fig.

9; and I Fig. 11 is a perspective view of a file of sheets held together by a fastener including a still further modified form "of backing member.

Referring to the drawings and more par ticularly to Fig. 1, the front member of the fastener there shown comprises the end portions 10 and 11 each formed with'an aper-,

ture 12 for one of the tongues of thebacking member and designed to rest on the top .sheet of'the file throughout the area surretain the tongues in bent down position; in

rounding the perforations 13 in the sheet, thus reinforcing the sheet against tearing out from the said perforations. The end portions of the top member are connected by a part 14 of less width than said portions and having a section 15 struck" up slightly from the plane determined by end. portions 10 and 11. This section 15 is shorter than the distance between' the end portions and thus. forms notches 16 and 17 In use, the tongues of the backing member are bent down and under section 15 and are thus retained against displacement. Preferably the section 15' projects over about one-halfthe width of the tonguesso that it is an easy matter to manipulate the tongues 6 1 to the apertures 312 bend them under the sections or free them therefrom. In this latter operation, the notches 17 afford a space for the fingers to push on the side of the tongues. If desired the part 14 may be reinforced by a rib or corrugation 18 bent out from the said part.

The top member shown in Fig. 4 is similar to that of Fig. 1 except that the tongue retaining section is formed in a somewhat different manner. Thus this top member comprises end sections 110 and 111 each formed with a tongue aperture 112. The part 114 which connectsthe two end portions has the section 115 struck up from the plane determined by the end portions, and this section .is of greater width than the remainder of part 114, thus extending down a suflicient distance so that the tongues may be bent down and under said section in the same manner as described in connection with Fig. 1, and also forming the finger. notches 116 and 117.

In Fig. 7 a front member is shown which comprises end portions 210 and 211 formed with the tongue apertures 212 and connected by the part 214, the middle portion of which is wider than the end portions thereby providing an extension 215 and the finger notches 216 and 217. In using this member the tongues are bent down and under the extension 215, the finger notches 216 and 217 forming sp'aces whereby the tongues are easily manipulated to disengage them from the extension. If desired the part 214 may 'be reinforced by a rib or corrugation 218.

In Fig. 8 another form of front member is disclosed which comprises the end portions 310 and 311 formed with the tongue f apertures 312 and connected by the part 314 h than the said end porwhich is of less widt tions and extends diagonally between them. Thus this part 314 crosses the line connecting and forms a retaining member for the tongues in a manner similar to that described in connection with the other forms of the front member. Further the arrangement of the connecting part 314 forms notches 316 and 317 for the fingers when disengaging the tongues from the retaining member. If desired the part 314 may be reinforced by a lengthwise extending corrugation or rib 318. i

In all of the above described forms of the front member, it will be observed that the connecting part is substantially of less width thanzthe width of the end portions and furthermore the joints between said part and "end portlons are disposed at one side of a 1meconnecting the tongue apertures. Be-

tion. The tongue 24 at the opposite end of the base is stamped out from material which extends beyond the base, as shown in dotted lines at 24 in Fig. 5. This tongue is then bent back on the base 20 and then through the aperture 22 to its right angularly proj ecting position. Thus the tongue 24 is connected to the base by a part 25 which extends between the foot of the tongue and the adjacent end of the base. In this manner the tongue 24 is disposed so that it projects from the base at a slight distance from the end thereof, thus forming the end portion 26 which rests against the bottom sheet of the file in the same manner as the opposite end portion 23. It will be observed that both tongues 21 and 24 are longer than half the distance between said tongues. Further by striking up tongue 21 from the base a considerable saving in material is made. If desired the base may be reinforced by the longi tud-inally extending corrugations 27.

Referring now to Figs. 9 and 10 a backing member is shown which comprises the base 28 and the tongues 29 and 30 bent up from material extending from the ends of said base. Thus the tongue 30 is bent from the position indicated at 30 back on the base 28 and, thence at right angles to the position shown in-full lines at 30. The tongue 30 is thereby connected to the base 2.8 by a part 31 which extends between the foot of the tongue and the adjacent end of the base. The tongue 29 is formed in a. similar manner being connected to the base by a part 32 which extends between the footof the tongue and the adjacent end of the base. Infthis manner end portions are formed on the base projecting outside the tongues and affording bearing portions which reinforce the bottom sheet against tearing out from the tongue perforations. If desired the doubled over end portions may be secured together by forming an aperture 33 in the base and striking up. a tongue 34 from the part 31 through said aperture and bending it down against the under side of the base in the corrugation 35 may be formed in the-base to strengthen the same. The length of the tongues is not limited and as shown are longer than half the distance between them measured along the base.

In the form of the invention shownin Fig. 11, the backing member comprises two similar parts 35 and. 36,. The part 35 has manner clearly shown in' Fig. 10. A rib or a tongue 37 struck up from the same, the

foot of the tongue being disposed slightly from the adjacent end of said part thus forming an end portion 38 hearing against the under side of the file outside of the.

v The two parts 35 and 36 are joined together by forming the fingers .42 and 43 at one end of part 35*, which fingers extend through the'sl'ot 44: in part 36 and are bent down against the opposite face thereof. In a like till manner one end of part 36 is formed with the slot 47 in part 35* and are bent down against one face thereof. Thus the two parts are locked together and if necessary at any time the distance between the tongues 37 and maybe adjusted merely by sliding one part on the" other. It will be'observed that the tongues are longer than half the distance between the foot portions thereof and further have the end bearing portions similar to the forms shown in Figs. ,5 and 9.

Although several forms: have been described in detail, it is to be understood that the invention is not limited to these forms but includes modifications and changes which 1 come within the scope of the appended claims.
